Title: Heat exchanger for a water heater
Inventor: AFSHAR MOHAMMAD REZA
IPC: F24H9/12
Filed: 1992-09-10
Granted: 2000-03-14
Abstract: A swimming pool or spa heater unit (10) having a heat exchanger manifold (28) designed to permit the use of direct plastic piping connections to the manifold header (33). The manifold is principally characterized by a header end having an inlet port (36) and outlet port (37) located on a level below the manifold inlets and outlets (32) communicating with the heat exchanger (34). The inverted arrangement of the header ports (36, 37) relative to the manifold inlets (32) and outlets (32) to the heat exchanger (34) permits unreturned water in the unit heated by residual heat from the heater (10) to form a temperature gradient therebetween which prevents the temperature of the water at the header connection from reaching a level incompatible with the use of direct plastic piping connections. The manifold is also integrally provided with weirs (40, 41) which serve to provide dry-fire protections for the heater.

Abstract: A weight distributing hitch for towing a trailer behind a vehicle includes a hitch bar for mounting to the vehicle and a ball mount head for mounting on the hitch bar at a selected tilt angle.  A pair of spring bars are mounted to the ball mount head.  These spring bars distribute the weight of the trailer relative to the vehicle.          Each spring bar is substantially L-shaped and includes a turned groove at a proximal end received in a cooperating aperture in the ball mount head.  A retainer of spring steel engages in the grooves to hold the spring bars in position.  The relative tilt angle of the ball mount head is adjusted by means of an eccentric angle adjusting element in the form of a washer.  This washer is fixed to one of the ball mount head or hitch bar and includes a cam surface for engaging the other of the two elements.  A method of adjusting the tilt angle is also provided.

Abstract: An ink conducting core for supplying ink from an ink container to a pen point is formed with an exposing recess in  the  vicinity  of  a  connecting  portion  of  the  ink conducting core with a middle core.  With this, even when outside impact etc. causes air bubbles to enter the ink conducting core, the bubbles may be ejected readily through the exposing recess whereby smooth ink supply can be secured all the time.    An annular groove and a small diameter portion is provided in the rear part of an ink conducting core.  An ink retainer  having  a  through-hole  through  which  the  ink conducting core is fitted is constructed such that the through-hole has a small diameter portion in the rear end thereof.   The ink conducting core is fitted to the ink retainer with the side walls of the annular groove engaging the small diameter portion in the rear end of the through-hole.          As a result, it is possible to securely restrict back-and-forth movement of the ink conducting core due to impact etc.
